TRANSPARENT CONCRETE: A SUSTAINABLE AND ENERGY-EFFICIENT BUILDING MATERIAL

ABSTRACT: 
Transparent concrete, also known as light-transmitting or translucent concrete, is a new composite that allows some light to pass through the inclusion of optical fibres or translucent aggregates within a cement mix. This innovation combines beauty with practicality, offering options for energy-efficient architecture. The material keeps enough compressive strength while letting in natural light; this reduces the need for artificial lighting and lowers energy costs. Research shows that how well light transmits depends on the type, diameter, and arrangement of the fibres mechanical strength mainly relies on how well the aggregates bond and the curing methods used. Developing transparent concrete is an important step toward sustainable and smart infrastructure. Its uses range from building facades to interior walls and walkways, serving both structural and decorative purposes. Studies suggest that it can help lower the carbon footprint of buildings by enhancing natural light. However, despite promising experimental results, challenges still exist in large-scale production, cost management, and durability over time. This study reviews current research to examine the performance, sustainability, and plan for using transparent concrete as a next-generation building material.
